Tryptophan-Derived Carbon Dots Detect Last-Resort Antibiotic in Cells and Water
Researchers report nitrogen and sulfur co-doped carbon dots made from L-tryptophan and thiourea that detect the antibiotic meropenem at nanomolar levels in live cells, serum, urine, and water. Subject of Research: A fluorescent carbon-dot nanoprobe for detecting the antibiotic meropenem…
